CVE-2026-56660 – GetSimple CMS: CSRF, SSRF, and Unrestricted Zip Extraction

​CVE ID :CVE-2026-56660

Published : Oct. 1, 2026, 8:17 p.m. | 1 hour, 4 minutes ago

Description :GetSimple CMS is a content management system (CMS), and GetSimple CMS CE is the community edition of that CMS. Prior to version 1.5, the update handler in UpdateCE.php downloads a ZIP archive and extracts its contents into the web root without validating file types or extraction paths. Because PHP files are written into a web-accessible directory, an attacker who can cause a malicious archive to be processed achieves remote code execution as the web-server user. Entry names are also used unsafely, allowing directory traversal (../) to write files outside the intended extraction directory. This issue has been patched in version 1.5.

Severity: 9.1 | CRITICAL
